DNSSEC Usage in Switzerland is on the rise after widespread attacks on the Domain Name System

Attacks on the DNS System

Cyber attacks on the DNS system are not new. Cache poisoning, Domain Hijacking and BGP injections of routes to public DNS resolvers happen regularly, but they usually don’t get much attention as they target the Internet’s core infrastructure and are not directly visible to end users in most cases. This time it was different. The recent widespread DNS hijacking attacks on several Mid East, North African and European and North American governments and infrastructure providers, published by Ciscos Talos showed that DNS attacks are a real threat to cyber security. Netnod, one of the affected infrastructure providers issued a statement, that called, amongst other domain security mechanisms, for the implementation of the DNS Security Extensions (DNSSEC).

The analysis of these attacks also convinced the Internet Corporation for Assigned Names and Numbers (ICANN) that there is an ongoing and significant risk to key parts of the System (DNS) infrastructure. ICANN issued a call for “Full DNSSEC Deployment to Protect the Internet” across all unsecured domain names.

The question is if  these attacks and the awareness that DNSSEC is an absolute essential base layer protection for domain names had some effects on the Implementation of DNSSEC Switzerland?

More DNSSEC signed domain names

As a ccTLD operator SWITCH publishes the number of DNSSEC signed .ch and .li domain names every month. While the number of signed domain names is still very low at around 3-4% we see a rise in the numbers of signed domain names for two years now.

Top 1000 .ch Domain Names

UPDATE 19.02.2019:

From February 2019 on there will be a few small changes. A co-worker, Antoine, has discovered a flaw in the current measurement of the top 1000 .ch domain names which has been removed by now. Since we only counted the number of distinct IP addresses per domain for both IP versions, using IPv6 one can easily send queries from a whole /64 range which results in approximately 1.8*10^19 different addresses. Being a private customer of the Swiss ISP Init7 even gives you an entire /48 range. Like that you can easily push a domain name to the top! In order to prevent this from happening we will now count the distinct number of ASes per domain.

Additionally, we will provide 2 lists from now on. One that contains a ranking based on ALL queries, i.e. including queries that have returned NXDOMAIN, and one whithout those NXDOMAIN queries. Previously, we just provided the former. Continue reading
